However, the completeness on a population level is unknown.

We conducted a nationwide retrospective cohort study aiming to evaluate the completeness of RET testing in the Danish MTC cohort. Additionally, we aimed to assess the completeness before and after publication of the first Danish guidelines and characterize MTC patients who had not been tested.Methods: The study included 200 patients identified from the nationwide Danish MTC cohort 1997-2013. To identify RET tested MTC patients before December 31, 2014, the MTC cohort was cross-checked with the nationwide Danish RET cohort 1994-2014. To characterize MTC patients who had not been RET tested, we reviewed their medical records and compared them with MTC patients who had been tested.Results: Completeness of RET testing in the overall MTC cohort was 87{\%} (95{\%} CI: 0.81-0.91; 173/200). In the adjusted MTC cohort, after excluding patients diagnosed with hereditary MTC by screening, completeness was 83{\%} (95{\%} CI: 0.76-0.88; 131/158). Completeness was 88{\%} (95{\%} CI: 0.75-0.95; 42/48) and 81{\%} (95{\%} CI: 0.72-0.88) (89/110) before and after publication of the first Danish guidelines, respectively.
